Is this MPPT? User review says it is not, Posted on Nov 6, 2013 5:44:13 PM PST "It seems that the Instapark 30A and 60A MPPT are not in fact MPPT"

This guy is really MPPT. There were some fake MPPT Instaparks here, but this really is (opened it up and it actually has beefy inductors as needed for MPPT, while the fake ones don't). Also I measured the input and output voltage/current and it really does DC/DC conversion between these to adapt to the load.

Yes it is. Im not sure why other reviewers have said this. I have been using this controller for over a year and it works as advertised. If you read my review it also sets other reviews off as mine is described under actual use none of the other reviews say why its not.

Yes the 2010 I had was MPPT. My cat made a mess on it and now it is a door stop...But, definitely MPPT...

I never really took the time to investigate. This piece of junk failed so fast, I was genuinely surprised. I don't think it is, and this was not a big seller here in the US. Sorry. My opinion is look for something else, this gets 2 thumbs down.

The MPPT-45 is really too small for 1KW solar pushing down to 12V. 600w of solar is the peak for that setup. So you need to get the FM-80 by Outback (1250w capacity) Thanks,

Hi Mr. Hogan,I installed a Kill-A-Watt from Radio Shack tonight. While using an internal Seagate 500GB hard drive the meter shows usage is 5 Watts and .07 amp draw. The figures are different from one electric provider to the next. As an example, my local electric company charges me 12 cents per kWh during peak season and 11 cents during off peak season. It's costing me $5.26 per/year running 24/7/365.It's been running flawlessly since December 25, 2012. Yes, over a year and I share family pictures to lots of family members. Very easy to use.I hope this helps.Thanks,Terry Mundy Hi Mr. Hogan,I installed a Kill-A-Watt from Radio Shack tonight.

yes, i use three 20 volt panels in series so i am putting in 60 volts. the MPPT type of controller means that it an take in any voltage (up to a max, i think 100volts for this controller) and converts it to 12 volts for charging the batteries.

All solar panels regardless, solid or folding have to be rated by wattage. As far as the 2 compare;they are both made in china. Myself I prefer Instapark because of the material and the hookup. Dealt with Instapark several times with great satisfaction.It was used this fall to go hunting and it kept all the cell phones charged.It was used with a jumpstarter;the kids played games all week on their cells and never wanted for power.

this is not a mppt controller. so it will work only in parallel panels not in series with your panels

MPPT is a little overkill. You need a 20A PWM controller like the morningstar ss-20-12V

I have never tried the Allpowers brand. I remember considering them but went with the Instapark due to the reviews being slightly better. Also the Instapark is smaller than the Allpowers.I bought the 10w first, and was happy enough that I bought the 27w. While I have not yet had a chance to run it throu all the paces, I can tell you that:on February 6th, in Portland OR (@45 parallel), the sun less than 30degrees above the horizon, full overcast with just enough sun coming thru to have very light shadows... I was able to charge my Samsung phone while it was on at about 12% an hour. Both the 10w and 27w work well in low light conditions. I have never tried the Allpowers brand.

Yes this is off grid, charge controller is a simple one not mppt. Wish it was. Solar panels work great have had hooked to a sun gti 500watt. I c 160 watts on avg out of these two panels. I bought this kit and two batteries so i could cover myself if grid went down. Good luck.

I have one sitting right in front of me now on a panel. I have a SunForce controller that is showing 12.7 volts when I switch over to monitor voltage and right below that is the Sunpro CP8215. The reason I have both is that I usually leave my controller switched to current as I don't want to wear out the switch going back and forth. The Sunpro is reading the same...as far as you can accurately interpolate. What I have discovered is that depending on where you put a volt meter, the voltage measured will vary a little. I also bought 2 digital cigarette lighter type gauges at the same time and they both varied by a volt or so. That was when I discovered about the difference where you took the measurement. Overall, I really like the Sunpro. Since it uses old technology lighting, I just disabled it as I don't want the useless battery drain. Having left it connected 24/7 over a year now it is still performing just fine. Hope this helps. BTY.. I would buy another. The black is fairly nice looking.

What brand of solar panels have the DC power port adapter for this version of this product? Instapark does not provide that adapter.

Yes, The MPPT charge controller does the input/output conversion internally to provide the most efficient charge voltage and current. Mppt controllers are about 30% more efficient than the old type.

M_ENGLE and DUSTY comments contradicts what Bob commented...I want to use this device for load testing and confirm the condition of any battery......who am i to be believe now, because am about to place order.

I've had the instapark 27w for several months now and wow it works great. The only issue but not a big deal make sure you utilize all the panels, meaning to make sure they are all open and facing the sun to maximize wattage gathering.

I own the Instapark 10W--I don't understand your question--you name two identical 10W items. I'm very happy with my 10W; it keeps my gate opener's battery charged. I had to drill additional holes (very carefully) to mount the unit. As delivered, it offers few mounting options.

My powerland is a 10k watts.... My other gen was a 5500 .... I forget the name but it came from lowes.....

There are two types of charge controllers; PWM and MPPT. I have 3x 100w panels ran in parallel to triple my charge amperage. This maintains the panels at 12v, but triples the amperage. I have a 30a charge regulator, which is PWM. I have read, though, that MPPT is the newest and best charging technology available. The PWM regulators are cheaper, but you get what you pay for. My next charge regulator will definitely be a MPPT. Google it. You'll figure out the difference between to two. Just be sure that you size your regulator bigger than your solar panel array for room to grow, and so that you don't constantly put your charge regulator under too much stress from incoming amperage. Here's the charge regulator I purchased http://www.play.com/Electronics/Electronics/4-/46835087/789550567/TomTop-30A-12V-24V-Intelligent-LCD-PWM-Solar-Charge-Controller-Solar-Panel-Battery-Regulator/ListingDetails.html?_%24ja=tsid:13315|cat:46835087|prd:46835087&ef_id=Udt8FQAABKfxcsgO:20130709151438:s It works well, but now is starting to be a little troublesome with the display just after 9 months of use. Spend a little more money and get one that is MPPT, and make sure you have an LCD screen. It's nice to know the charge, draw, and basic voltage of your battery bank.
